Loading And Unloading With Trailer - Komatsu ecot3 Operation And Maintenance Manual

OPERATION

LOADING AND UNLOADING WITH TRAILER

Always obey the following when loading or unloading the machine from a
trailer.
Select firm, level ground when loading or unloading the machine.
Maintain a safe distance from the edge of the road.
Always turn the auto-deceleration switch OFF (cancel).
If the auto-deceleration switch is left ON, the machine may suddenly
start moving.
Always set the travel speed switch to low speed (Lo), run the engine at
low idle, and operate the machine slowly when loading or unloading.
In cold areas, carry out the warming-up operation thoroughly and make
sure that the engine speed is stable before carrying out the loading or
unloading operation.
Never correct your steering on the ramps. There is danger that the
machine may tip over.
If necessary, drive off the ramps or back on to the trailer and correct the
direction.
It is dangerous to use the work equipment for loading and unloading
operations. Always use ramps.
When on the ramps, do not operate any lever except the travel lever.
The center of gravity of the machine will change suddenly at the joint
between the ramps and the trailer, and there is danger of the machine
losing its balance.
Travel slowly over this point.
If it is necessary to swing the work equipment on the trailer platform, the
footing is unstable, so be extremely careful that the machine does not
tip over.
If the work equipment is installed to the machine, pull the work
equipment in, and operate slowly to prevent the machine from losing its
balance.
Position a flagman to give guidance to prevent the machine from
coming off the ramps and to ensure safety in the operation.
Always observe the following regarding the ramps and trailer platform.
Use ramps with ample width, length, thickness, and strength and install
them at a maximum slope of 15 degrees.
When using piled soil, compact the piled soil fully to prevent the slope
face from collapsing.
Clean the machine tracks and ramps before starting in order to prevent
the machine from slipping on the ramps.
There is danger of the machine slipping if there is water, snow, grease,
oil, or ice on the ramp surface.
When loading or unloading, always use ramps or a platform. Proceed as follows.
